Hello to all the Lowfers, i am a little off air for job problem, so hope to be soon in air on 136. Well here in Italy, with Associazione Radioamatori Italiani, the ARI, we are planning to put in air
Hi Mal, i not agree with your comment, here i have made many test with narrow band in QRSS, but using or not using an external DSP is exatly the same, i have aTimewave 599zx, but for qrs no differenc
Mal, we have here a unit W&G SPM 12 that run 24 hours at day used for our relay LF to 2 meters FM, the filters used is the 1800 HZ, without AGC, and powered from a 12 VDC voltage battery, in this way
One of the reasons cited in the FCC Notice of Proposed Rulemaking is an objection filed by Texas Instruments, who make "smart card" readers that work at 121 kHz. They're afraid hams are going to ope
Dear LF Group, ............ I did have a complete 2 way CW QSO with IK2DED, who has been putting an excellent signal into the south of England after dark lately, usually about 569. Cheers, Jim Morit
Mmhhhhh, to many criticism in LF reflector!!!! I think that ALL the operation that may improve the activity in 136 is welcome, and this operation is one of this, in other way, we may sleep for all th
Hi Jim, I'm sorry but i have not implemented the power attenuator to reduce the power of 10 and 20 dB beacouse the express courier have lost my components that i have ordered ten days ago at RS Compo
May some DL friends explain me in few word the article made by DF8ZR "Aktive antenne fur Langwelle", pubblished on the web site of ON7YD?? Is that an E field antenna with a narrow bandwidht for 136?
Has someone tried the E-field probe vertical whip with high impedance fet preamplifier, comparing it to a classic multiwire receiving loop, here in 136 Khz? I would like to made an E-field probe for
Hallo to all, i inform all the LF comunity that is now on the air a beacon located here in North Italy, few kilometers west of Garda Lake, at the top of a mountain, 980 meters above sea level. The fr
The same received here in North Italy, may be qsy 137.370 qrss 30 ??? By and say hallo to EA1LQ Ernesto hope soon in 137 khz, Jose!!!! 73 de Giulio IK2DED. -- Original Message -- From: [email protected]
Hi Alex and all, soon i'll measure exactly the antenna current, but one things that appear in this discussion, is that the antenna work very well, it is only a single wire 60 meters long about 1 mete
Hi Alex, If can i help Vlad, i may send him a two little fixed frequency source for qrss at 136, 670 KHZ more or less some hertz, and one at 136, 500 KHZ for aural CW. This source are made with two x
Hi to all, yesterday i have retuned the beacon at exatly 135,710 KHZ, with a new xtal divided 81 times, so i think now it will be very stable! I have made some comparisasion tests on my RX antennas a
Also here i have seen the same at about 20.30 Z. Then this signal is fadeed down. Received at exatly 136.100, 1 hertz more or less, with my new E- Field probe. 73 Giulio Scaroni IK2DED. What is Vlad
Hi to all, i have received by Crystalonics the CP666 High Performance FET for the AMRAD E Field Antenna, so in this weekend i have realized it. The first impression is that i can't believe that with
Hi hi hi Alan, i hope my little beacon is not so important that may switch on the SVX again hi hi hi.. But for prevent any form of interference with this service i have ordered just this morning a xt
Yes also here the station is heard with very strong signal yesterday, but seems not active all the day. But this station is a commercial or military installation??? I'm afraid that with the winds of
Hi Alan, about the frequency is really few hertz below 135.800 KHZ. About timing also here is little annoing to stay for all the cicle to receive the 3 power levels, the message may be changed in thi
Hi to all, finally i have implemented the variable power level in the beacon, now the mode and message are like below: start with IK2DED/B LF BEACON JN55FO 3 times speed 7 wpm power 40 W then IK2DED/
